The Seguso black and red figure has the rarer black label which I've only come across a few times and I believe is from the 1980's though I've never managed to get this confirmed by the factory, but a nice and scarce figure.
The third piece colours scream Poli and Seguso but the applied handle and foot argue against this as the only pieces I've had in this colour combination have had integral handles and been signed to the base.
The applied handle and base have more of a Salviati look about them in which case mid 1960's to around 1974.
